Closing the Copy,Link,Move destination pop-up before it finish loses rendering at next use.

1. Start a Link operation
2. While the tree is rendering (throbbers show) close the dialog
3. Enter the dialog again and an improperly rendered largely non-functional tree will be presented

Workaround: Wait for the improperly rendered tree to complete if needed.  Close the dialog.  Try again.  Usually it will render correctly.
